Hi Bart,

I noticed you stated that you hook one of the "ears" of your double
bushing pole pig AND the case to RF ground. In my pole pig coil, I
also hook one of the ears to RF ground, but I hook the case of the
pig to the mains ground. I'm not sure which is best, but I do know 
that w/ a double eared pig, the case is completely electrically isolated
from either end of the HV winding of the transformer, so you can run 
the RF/mains ground in the way that I do it and keep them properly 
seperated. I suppose it's a matter of preference. You are absolutely
correct about the control panel surfaces shocking you if you do not
keep the RF ground seperated from it, though.
